While saving Susie from the Sound of Justice's attack in the dark, Kris shows a unique animation. We only see a glimpse of it in a flash of light from the statue hitting their shield, but the full animation looks like this:

There are black pixels in the sprite that you can't see if you're in dark mode. There's also another version of this sprite that is unused, and doesn't have the black pixels:

I think those should be added to https://deltarune.wiki/w/Kris_Dreemurr#Gallery. It is a really cool animation that is usually obscured by special effects. People would like to see what it looks like.
It wouldn't feel out of place among other situational sprites in the Gallery.
